I chose these two because sweet potato are a great source of Vitamin B6 and C as well as Iron and Magnesium while bananas are great for potassium and vitamin A.
I used 1/2 a large sweet potato to make about 72g of dehydrated chips and 3 bananas which yielded about 35g of dehydrated product.
Sweet potato chips
for the sweet potato chips, I first run 1/2 of the sweet potato over a mandolin to get nice even slices. Then I combined some rock slat, oil (about 5 second spray) and about a teaspoon of dried oregano leaves together with the slices (mix this by hand to ensure and even coating). Lay them out on the dehydrator and re sprinkle any salt left at the bottom of the bowl. I used four trays and left them running for about 8 hrs (you know that they are ready as they snap rather than bend). Put into individual bags
Dehydrated Banana Slices
Because I am trying to eliminate added sugars, I decided to use really ripe bananas which are already naturally sweet. I once again used the mandolin to get nice even slices, but I think I will use a bigger setting next time or an egg slicer, as the setting I used made the slices little too thin. I placed them onto two trays and left them to dehydrate for about 10 hours (until firm).
